Mounting Instructions
1. Use a large ground pad area near device pins 1, 2,
4, and 5 with many plated through-holes as shown.
3. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.
Part Identification Marking
The part will be marked with an “A22” designator on
the top surface of the package.

Pin # Function
Description
3
RF IN RF input pin. This pin requires the use of
an external DC blocking capacitor
chosen for the frequency of operation.
1, 2, 4,
5
6
GND
Connection to ground. Use via holes for
best performance to reduce lead
inductance as close to ground leads as
possible.
RF OUT/
BIAS
RF output and bias pin. DC voltage is
present on this pin, therefore a DC
blocking capacitor is necessary for
proper operation.
Caution: ESD sensitive
Appropriate precautions in handling, packaging
and testing devices must be observed.
